Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25900, here are decompositions:

11 + 25889 = 25900
53 + 25847 = 25900
59 + 25841 = 25900
101 + 25799 = 25900
107 + 25793 = 25900
137 + 25763 = 25900
167 + 25733 = 25900
197 + 25703 = 25900

Showing the first eight; more decompositions exist.
